“…Considering it necessary to research the theoreticalmethodic turns of the ecologically-dependent diseases' problem, the authors made the analysis of the conducted theoretical and practical researches of the population's sick rate's problem and indicated the methodological landmarks strictly for the geographic sciences: -the problem of the population's sick rate is almost not determined without the getting used to the space-time continuum. The first scientific researches in this direction didn't deal without the geographic maps [10]; -the spreading of the sick rates in the form of the epidemics, epizootics or epiphytes expresses the aspiration for the model "center-outlying area" [11], generally known in the geographic sciences, and still further -the theory of the innovations' diffusion of T. Hegerstrand [12,13]; -the majority of the medical-geographic researches is connected with the natural centers of the diseases' appearance and uses the landscape-scientific approaches [14]; -the medical-geographic researches of the ecologicallydependent diseases (changes of the arterial pressure, the disease of the respiratory organs' systems, the urinarysexual system and others) are more frequently connected with the anthropologic-genetic changes of the environment (the contamination of the atmospheric air by dust and chemical combinations, the radio-active contamination, the influence of the electromagnetic artificial fields and noise on health) [15,16]; -the joint task of the Medicine and Geography is the search of the ways of the optimal interaction between the individual, economy and environment, both as the natural one and as the one, created by him (her) [17], the same tasks are solved by the conception of the stable development [18,19]; -the single conception of the non-zero or the accepted risk dominates at the present time, because the risk's level in any system cannot be equal to zero and it changes in the limits of the probability from 0 to 1, where 0 is the probability of the absolute inertness (the event does not happen in any case), 1 is the risk is realized (the event has happened) [20]; -there is no distinct definition of the notions social, ecological, medical risk, the risk of the human diseases' appearance. There is the notion "environmental risk" [21] in the foreign publications as the risk for the human health in the result of changes of the environment's quality; there is the notion "risk factors in health and disease" [22], in which the ecological factors, influencing the health state of the individual and the appearance of the diseases, act as the separate component.…”
